Butman Township WWSL Wastewater Treatment Plant, Michigan

Butman Township WWSL is a municipal wastewater treatment facility located in Butman Township, Gladwin County, Michigan, United States. The plant serves a population of approximately 1,947 residents, reflecting a small community scale typical of rural Michigan townships. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for most municipal facilities. Secondary treatment involves biological processes to reduce organic matter and suspended solids. The plant's designed capacity is 2,271.24 units, with a current discharge volume of 75.71 units, indicating it operates well below its capacity. The treated effluent is discharged into local waterways that ultimately drain into the Saginaw Bay of Lake Huron, part of the Great Lakes system. This watershed supports diverse aquatic life and is important for regional water quality. The plant's performance is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program administered by the Michigan Department of Environment, Great Lakes, and Energy (EGLE).

The plant discharges into tributaries of the Saginaw River system, which flows into Saginaw Bay, a shallow, nutrient-rich embayment of Lake Huron. This watershed supports important fisheries and migratory bird habitats. The Great Lakes ecosystem is sensitive to nutrient loading, making effective wastewater treatment critical for preventing algal blooms and maintaining water quality.
